A student was given a dry pycnometer (a flask and its fitting glass stopper), an unknown liquid, and unknown solid. She was tasked to determine experimentally the density of the unknown liquid and solid.

Using the following two set of data were collected, determine the density of the unknown liquid and solid.

The density of Liquid:

Mass of empty pycnometer ____54.308____ g

Mass of pycnometer and water _____79.114___ g

Mass of pycnometer and unknown liquid ______73.605__ g

Temperature in the laboratory _____20.0____ C

Density of water at 20.0 oC ___0.9982___ g/cm3

Mass of water =

The volume of water =

Mass of liquid =

The density of liquid =

The density of the Solid:

Mass of pycnometer and unknown solid ___95.328_____ g

Mass of pycnometer, solid, and water ___107.672____ g

Mass of water =

The volume of water =

Mass of solid =

Density of solid =
